Specification of Letters Patent.

Patented June it, rare.

Application filed December 22, 1917. Serial No. 208,454.

To all whom it may concern:

Be it known that I, THOMAS M. SHANK, a citizen of the United States, residing at Bidwell, in the county of Gallia and State of Ohio, have invented certain new and useful Improvements in Grain-Cleaning Devices, of which the following is a specification.

This invention relates to grain cleaners and the primary object of the invention is to provide an improved construction for grain cleaning sieves of the type commonly employed on various kinds of grain cleaning machinery.

The principal object of the invention resides in the provision of a removable container carried by the sieve at a point approximately intermediate the ends thereof, and adapted to receive bits of metal which are often found with grain.

A further object of the invention is the provision of a device of this character which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordi narily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and accompanying drawings wherein is illustrated the preferred form of my invention, in which Figure 1 is a plan view of a sieve showing my invention applied thereto.

Fig. 2 is a longitudinal section through the same.

Referring to the drawings, wherein is illustrated the preferred form of my invention, in which like numerals of reference indicate corresponding parts throughout the several views, the sieve indicated generally at A includes the side frame bars 1 and the end frame bars Q. Mounted upon the upper edges of these frame bars is a perforated plate 3 which forms the sieve and which may also consist of a strip of any suitable foraminous material. Intermediate the ends of the strip, a portion of the same is cut away to provide a substantially rectangular opening 4: extending transversely across the sieve. This arrangement provides two end pieces of sifting surface which have their proximate edges spaced apart for a distance equal to the width of the opening 4. These proximate edges are attached to supports 5, the ends of which are fastened in any suitable manner to the side frame bars 1. Attached to the bottom of the supports 5, at each end thereof, is a strip of any suitable material as indicated at 6 and these strips are adapted to receive and support a re1novable receptacle 7 adapted to be placed in the opening 4 and be held between the arms or supports 5 while the bottom of the receptacle rests upon the strips as indicated bydotted lines in Fig. l of the drawing. This receptaclc is provided on the inner surface of its end wall with a handle 8 which may be grasped for facilitating mounting and re; moval of the receptacle from the depressed portion of the sieve.

The marginal edges of the sieve, mounted upon the top edges of the frame are held thereto by fastening strips 9 which overlie the margins of the sieve and are fixedto the frame. The strips embrace a portion of the frame in which the grain is received when it is being sifted. During the sifting opera tion advantage is taken of the fact that most of the bits of metal are heavier than the grain and consequently when the sieve is in operation the objectionable pieces of metal will be worked toward the receptacle 7 and deposited therein while the grain being of lighter weight and also of small size in comparison to the size of the objectionable metal will be sifted through the perforated sifting surface thereby causing only the objectionable metal to be retained in the receptacle 7. The receptacle may be readily removed for dumping the contents thereof, and the grain cleaning surface of the sieve is thereby kept comparatively free of all spurious matter, while the grain is free to sift through the openings therein.

From the foregoing it will be observed that a very simple and durable grain cleaning device has been provided the details of which embody the preferred form. I desire it to be understood, however, that slight changes may be made in the minor details of constructions without departing from the spirit of the invention or the scope of the claims hereunto appended.

I claim.

1. In a grain sifting sieve, the combina tion of a frame having a foraminous sifting screen mounted thereon, and a removable receptacle mounted intermediate the ends of the sieve and removably supported by the said frame.

2. In a grain sifting device, the combination of a frame having a foraminons sieve mounted thereon, the said sieve having an opening provided intermediate its ends extending from one side to the other of the said frame, the supports carried by the frame, and a removable receptacle mounted in the opening and carried by the said support and disposed in a plane below the plane of the said sieve.

3. A grain cleaning device comprising an elongated sieve having a frame and a strip of foraminous material mounted on the frame, the foraminous material having an opening approximately intermediate its ends to divide the said sifting surface into the tWo end portions, the supports carrying the proximate edges of the said portions, and a removable receptacle mounted in the said opening and engageable With the said sup port, the latter having strips attached thereto for supporting the said removable receptacle.

In testimony whereof I aflix my signature in presence of tWo Witnesses.
